DRIVE MECHANISM.

Specification of Letters Patent.

Patented Sept. 21, 1909.

Application filed April 2, 1909. Serial No. 487,472.

To all whom it may concern:

Be it known that I, CHRISTIAN JENSEN, residing at lalmyra, in the county of Burlington and btate of New Jersey, have invented certain new and useful improvements in Drive lVlechanism, of which the following is a specification.

My present invention is an improvement on the drive mechanism disclosed in my copending application filed Nov. 27, 1908, berial No. 404,582, and it primarily has for its object to simplify the construction of the several parts and make them more effective in their operation.

In the present invention I provide an oscillating shaft having a weighted arm for eifecting a part of the oscillatory movement of the shaft, which shaft has a pair of cam engaging arms to cooperate with cams on a cam shaft that is geared with the cylinder shaft to be actuated directly therefrom. A forked arm on the oscillatable shaft receives a rod that is connected with a belt shifter and actuates the same.

My invention also includes those other novel details of construction, combination and arrangement of parts all of which will be first described, then be specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1, is a perspective view illustrating the application of my invention. Fig. 2, is another perspective view taken from a different position. Fig. 3, is a top plan view of my invention. Fig. 4, is a section on the line 44 of Fig. 3. Fig. 5, is a section on the line 5-5 of Fig. 3. Fig. 6, is a detail section on the line 66 of Fig. 7. Fig. 7, is a plan View of the parts shown in Fig. 6. Fig. 8, is a detail section of a part of my invention. Fig. 9, is a detail perspective view of the two cam engaging arms. Fig. 10, is a detail perspective view of a part of my invention.

' Referring now to the accomoanving drawings in which like letters and numerals of reference indicate like parts, 1 represents the washing machine casing and 2 the cylinder shaft which projects through the casing head and carries a master gear 3 and a pinion 4.

A bracket 5 is secured to the cylinder head, in bearings 66 of which, driving shaft 7 is mounted. Pulleys 8, 9 and 10 are mounted on the shaft 7, two of which, 9 and 10, are loose on the shaft, and the other, 8, is fast thereon.

A pinion 11 on the shaft 7 meshes with the master gear 3 on the cylinder or driven shaft 2, while the pulley 10 has a pinion 12 that meshes with an idler pinion 13 on a stub shaft 14, the pinion 13 in turn mesh ing with the master gear 3.

The outer bearing 6 of the shaft 7 has an extension 6 to receive the collar, or bearing portion 16, of a bracket 15, the bracket 15 being adjustably secured in place by a set screw 17.

The bracket 15 has a right-angled extension 18, terminating in a bearing 20, for the crank shaft 21 and has an aperture 19 to receive the bevel gear 22 that is secured to the shaft 21. A crank 23 serves to rock the shaft 21 in its bearing 20.

On a stub shaft or bolt 24 that is secured to the extension 18 by a nut 25, is a bevel gear 26 that meshes with the gear 22 and has a hub 27 to receive the collar 28 of the belt shifter arm 29, whose free end has an aperture 30 to permit passage of the driving belt 60. The arm 29 is secured to the hub 27 by a set screw 29*.

Stops 31 are provided on the collar 28 to engage a fixed stop 32 secured to the bracket part 18, the stop serving to limit the swinging movement of the arm 29 and gear 26 on the shaft 24.

33 is an arm pivoted to the crank 23 at 34 and secured to the shifting rod 56 at 33.

A second bracket 35 is secured to the cylinder head and has bearings 36 and 42 for the shafts 37 and 43 respectively. The shaft 37 is the cam shaft which carries a cam member 38 having a pair of cams 39 and 40.

A gear 41 on the shaft 37 meshes with the inion 4 and serves to impart motion to the cam shaft 37 directly from the cylinder shaft 2.

The shaft 43 is the oscillatable shaft to which the cam engaging arms 48 and 49 are secured to cooperate with the cams 39 and 40, respectively. The shaft 43 also has a forked arm 54 forked at 55 to receive the shifting rod 56. A socketed member 44 is secured to the shaft 43 by a set screw and receives an arm 46, on which is an adjustable weight 47 that serves to move the shaft 43 during a portion of its oscillations. Each arm 48 and 49 has a portion 50 that bears:

engage the forked arm 54 to limit themove ment of the rod, while an adjustable weight 53 counterbalances the rod 56 in its fulcrum on theforked arm 54, p

A11 arm 59 is-securedto the bracket, 35 to project adjacent to the arm 54 by a set screw 58 that passes through a slot 57 in the arm 59, so that by removing the rod 56 from the forked arm 54 and placing it over the arm 59 with the stops 5l52, one on each side of the arm, the belt will be held on the central or loose pulley and the driving shaft 7 will remain at rest.

Operation: Assume the belt 70 to be turning in the direction of the arrow in Figs. 1, 2 and 3, and assume that it is now located upon the pulley 8, motion will then be imparted to the shaft 7 to. turn the cylinder 2 in a clockwise direction in Fig. 1, thus imparting a counter-clockwise movement to the cam shaft 37. As soon as the cam 40 engages the portion 50 of the arm 49, it will turn the shaft 43 in the same direction as the shaft 37, to move the weight 47 in the direction of the arrow in Fig. 1, which weight, as soon as it passes the dead center will rapidly complete thev movement of the shaft 43 in such direction. The movement of the shaft 43' causes the rod 56 tobe moved from right to left in Fig. l, and impart its motion to the crank 23 to turn the shaft 21 in the direction of the arrow in Fig. 6, thereby turning the gear 26 and the belt shifter 29 in the direction of the arrow in Fig. 7 to shift the belt from the pulley 8 onto the pulley 10. Now as the belt is shifted on the pulley 10 the cylinder shaft 2 will be turned in a counter-clockwise direction to. impart motion to the cam shaft 43 in a direction opposite to the arrow in Fig. 1, until the cam 39 engages the portion 50 of the foot 48 which will cause the oscillatable shaft 43 to be oscillated and move the weight 37 in a direction opposite to the arrow in Fig. 1, which weight as it passes the dead center will complete the oscillatable movement of the shaft 43. The movement of the shaft 43 will thus shift the rod 56 back to the position shown in Fig. 1, and in consequence thereof the belt shifter 29- will be shifted in a direction opposite to the arrow in Fig. 7', to return the belt 7 0 onto the pulley 8 when the foregoing cycle of operation will be repeated.

WVhen it is desired to stop. the mechanism the operator may lift the rod 56 out of the fork 55 of the lever 54 and place it on the member 59 with one of the steps 51 on one sideof. the-.member59i and the other stop; 52 on the. other side of. the member 59 to; hold tliebelt shifting member 29 in its mid-position, indicated in F igi 7, to retain the belt:

invention will be readily understood by those skilled in the art to which it appertains.
